A Western blot analysis of phosphorylated Smads in primary osteocytes stimulated with a high dose of TGFβ1 for 3 days. B Expression of BMP-pSmad1/5/8 downstream target genes in primary osteocytes treated with varying concentrations of TGFβ1 for 3 days. C Intracellular pH changes in response to different concentrations of TGFβ1. D Expression of osteolytic factors in primary osteocytes induced by different concentrations of TGFβ1. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
